Authentication details provided was rejected by Source server. Kindly provide valid username and password.
I have a Zoho Mail.
I started to use Zoho CRM because of email marketing.
When I go to email configuration and try to link my Zoho Mail the following message appears: "Authentication details provided was rejected by Source server. Kindly provide valid username and password."
What can I do?
I want to link my Zoho Mail...
